Title: I want to find out who is using a database

Hi Everybody,

I want to drop a database and recreate it from a backup file.
But when I issue a dropdb command it wouldn’t let me do
so.  It tells me: database xxxxx is being accessed by other
users.

Can somebody please tell me how I find who it is using the
xxxxx database?

Thank you.

Regards,
